You don't need a gym or even fancy equipment. Airports have everything you need: plenty of space to move around, a moving walkway as your treadmill or the escalator as your stair-climbing machine. You can even use your bodyweight or your luggage for resistance training.
All you need is some creativity—and the willingness to look a little silly. After your workout, don't forget to clean up in the bathroom and put some deodorant on before getting on the plane; the person sitting next to you will appreciate it.
For all of these exercises, do three sets of 10 to 15 repetitions with 1-minute rest.
Push-Ups1 of 7
From a standard push-up position with hands slightly less than shoulder-width apart, lower yourself down until your chest touches the floor. Push yourself back up until arms are straight. This exercise targets your chest. You can modify the exercise by placing knees on the floor and flexed to 90 degrees with ankles crossed.
Squat Jumps2 of 7
With hands on hips in a squat position, jump straight up as high as you can. Upon landing, lower back into a squat position in one smooth motion, and immediately jump up again. This exercise works your quadriceps and butt.
Dips3 of 7
Grip the edge of a chair with hands about shoulder-width apart. Extend both legs straight in front of you with heels on the floor or on another chair facing you. Bend arms to lower your body and push back up. This exercise targets your triceps.
Biceps Curls4 of 7
Standing with feet shoulder-width apart, hold a small piece of luggage or a suitcase in front of you with palms facing up. Keeping elbows stationary, curl the suitcase up toward chest. Lower the suitcase down to your original position. This exercise works your biceps muscles.
Arm Raises5 of 7
Stand with feet shoulder-width apart and arms straight down at your sides with palms facing behind you. Raise a small piece of luggage or a suitcase up in front of you, keeping your arm as straight as possible until it's parallel to floor. Lower luggage back down to the start position. This exercise targets the front of your shoulders. To work the middle portion of your shoulders, raise luggage out to the side until parallel to floor.
Crunches6 of 7
Lay on your back on the floor, lift your legs, bend your knees, and cross your feet at the ankles. Place your hands across your chest or behind your head. Contract your abs, lifting your shoulder blades and upper back off the ground. Crunches target your abdominal muscles.
